Good question, I recently saw on a DIY forum folks discussing the merits of linear or SMPS for Hypex NCore based amps. First of all my view is that the best sound from Hypex NCore NC500 modules is with the recommended SMPS1200A700. A USA based company is recently offering a new range of multi channel NCore amps at around 200W per channel. A closer look at the spec sees they are using a linear PSU. So they must be NCore NC500 amp modules? Why only 200W? and why Linear PSU? Wi
